1. Bone marrow

   Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells. In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bones of the pelvis. Bone marrow comprises approximately 5% of total body mass in healthy adult humans, such that a man weighing 73 kg (161 lbs) will have around 3.7 kg (8 lbs) of bone marrow.Human marrow produces approximately 500 billion blood cells per day, which join the systemic circulation via permeable vasculature sinusoids within the medullary cavity. All types of hematopoietic cells, including both myeloid and lymphoid lineages, are created in bone marrow; however, lymphoid cells must migrate to other lymphoid organs (e.g. thymus) in order to complete maturation. Bone marrow transplants can be conducted to treat severe diseases of the bone marrow, including certain forms of cancer such as leukemia. Several types of stem cells are related to bone marrow. Hematopoietic stem cells in the bone marrow can give rise to hematopoietic lineage cells, and mesenchymal stem cells, which can be isolated from the primary culture of bone marrow stroma, can give rise to bone, adipose, and cartilage tissue.

1. bone marrow

   Bone marrow is a soft, spongy tissue that is found in the hollow interior of long bones such as the hip and thigh bone. It is responsible for the production of red blood cells, white blood cells, and platelets. There are two types of bone marrow: red marrow (which produces blood cells) and yellow marrow (which stores fat). It plays a crucial role in the immune system and is essential for overall health.

1. Bone marrow

   Bone marrow is the flexible tissue found in the interior of bones. In humans, red blood cells are produced in the heads of long bones, in a process known as hematopoesis. On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms, bone marrow accounts for approximately 2.6 kilograms. The hematopoietic compartment of bone marrow produces approximately 500 billion blood cells per day, which use the bone marrow vasculature as a conduit to the body's systemic circulation. Bone marrow is also a key component of the lymphatic system, producing the lymphocytes that support the body's immune system. Bone marrow transplants can be conducted to treat severe diseases of the bone marrow, including certain forms of cancer. Additionally, bone marrow stem cells have been successfully transformed into functional neural cells, and can also potentially be used to treat illnesses such as inflammatory bowel disease.

1. Bone Marrow

   The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

Examples of bone marrow in a Sentence

1. Bobby Elesky:

   There were times when the air quality was so bad that you would just drop to your knees and throw up, we made jokes at the time because we had no idea how serious it was.’ But Elesky says he found out when he returned home in 2005 and was told during a checkup that he had nearly 20 parasites in his body. More than a decade after his return, Elskey has suffered from myriad health issues, including plasmacytoma -- a condition where rare tumors attack soft tissue in the nasal cavity or bone marrow. He is grateful for the treatment he has received from the VA, but said the bureaucracy was difficult to deal with. Elesky said he was initially denied enrollment into the U.S. Department of Veteran Affairs’ Burn Pit Registry -- which was created to research and examine the potential threats from burn pit exposure.

2. Maureen Nemetski:

   I drilled a hole into her shin bone and placed an intraosseous line -- a bone catheter -- so that we could inject platelets and medications into her blood through her bone marrow. I can not imagine her parents' horror on hearing the crack of the drill bit into their baby's leg, we took turns pounding on this baby's chest and trying to pump air into lungs that had filled with blood.

3. David Mazie:

   This is not a situation where we want people to be worried about and not to proceed with donating bone marrow, the case is about an anesthesiologist who didn't do what Derrick Nelson was supposed to do. This doctor didn't do his job.

4. Dileep Yavagal:

   Previously it was thought that they transform into neurons and brain tissue, but especially with bone marrow cells that does not seem to be the case, the main effect seems to be through the supportive functions or nursing functions.

5. Bhavisha Patel:

   I believe that is what is challenging when we think about treatment, because it’s so heterogeneous, both at NIH and worldwide, the groups that have dedicated themselves to VEXAS are looking for medical therapies to offer to other patients who don’t qualify for a bone marrow transplant.
